Here's your problem. I bet the Lilliput looks great because the signal from the computer is a VGA signal. The TFT monitors want a NTSC/PAL signal. The VGA signal is going to look crappy when converting to a NTSC/PAL signal. Plus, you are splitting the signal between the two monitors so that is going to degrade the quality greatly. A Video amplifier will probably help while viewing videos and such on the two TFT monitors but will still look crappy while viewing the desktop.
